What happened here, topped on April 25th?
Hello fellow ents, I'm a newbie when it comes to cultivation. This is my second season growing (outdoors). Plant in question sprouted April 4th and is Honey Cream from RQS. As the title says I topped on the 25th of April. Got two main branches then another branch starting growing from the stump. A quick search has told me this is a "FIM". I guess I'm curious as to how this occurred, did I leave too much of a nub? I clipped right below the 4th node and there was around 1/4" of stem left above the 3rd node. I also topped a Special Queen 1(RQS) on the 25th, clipped the 4th node however there was closer to about an 1/8" of stem above the 3rd node this time. She just has the two main branches.
Is there an advantage to "fiming" rather than topping? Thank you all in advance!
